The 2026 instruction update
IRS published the 2026 Form 2290 instructions on April 12, 2026 covering the tax year July 1, 2026 to June 30, 2027. The most consequential change is administrative: the e-file mandate threshold dropped from 25 to 10 vehicles per filer, mirroring the IRS-wide push toward electronic information returns under the Taxpayer First Act.
Per-truck HVUT tax amounts are unchanged. Vehicles weighing 55,000 lbs in taxable gross weight pay $100 annually. Each 1,000-lb increment above 55,000 adds $22, capped at $550 for vehicles 75,000 lbs or heavier.
Why the threshold change matters
Small fleets with 10–25 power units who used to mail paper Form 2290s must now e-file through an IRS-authorized provider. Most providers charge $30–$70 for a single-vehicle return; multi-vehicle filings are typically priced per-vehicle with volume discounts.
The upside: e-filing returns the stamped Schedule 1 same-day, while paper filing took 4–6 weeks. Carriers waiting on the Schedule 1 to renew IRP plates or to prove HVUT payment at a roadside inspection benefit immediately from the faster turnaround.
Filing logistics
IRS recommends filing by the August 31 deadline for any vehicle in service on July 1. Trucks first used after July are due the last day of the month following the first-use month - a truck first used September 4, 2026 is due by October 31, 2026.
Penalties run 4.5% of unpaid tax for each month or partial month late, plus monthly interest. The IRS HVUT page is at irs.gov/forms-pubs/about-form-2290.
